LOW POWER QUAD
OPERATIONAL AMPLIFERS
Features
Description
The GM324, a quad internal frequency
compensated operational amplifiers with true
differential inputs, which operate from a single
power supply over a wide range of voltages.
They have several distinct advantages over
standard operational amplifier types in single
supply applications. The quad amplifier can
operate at supply voltages as low as 3.0V or as
high as 32V with extremely low quiescent
current (on a single amplifier basis). The
common mode input range includes negative
supply, thereby eliminating the necessity for
external biasing components in many
applications. The output voltage range also
includes negative power supply voltage.
Application areas include transducer amplifiers,
DC gain blocks and all the conventional op-amp
circuits which now can be more easily
implemented in single power supply systems.
For example, the GM324 can be directly
operated of the standard +5V power supply
voltage which is used in digital systems and will
easily provide the required interface electronics
without requiring the additional ±15V power
supplies.
